【摘要】：目的探讨颈椎椎弓根进钉参数与棘突的三维关系,为经皮椎弓根螺钉内固定及器械的设计提供参考。方法 20例健康成人颈椎CT重建模型导入UG imageware 13.2,以70%、80%、90%边界深度为研究基础,测量椎弓根通道进钉螺钉半径、外偏角、通道长度(L)、通道与矢状面、水平面的角度;进钉轴与冠状面的交点与椎弓根的角度。B、C点到参考平面、棘突的距离。结果 (1)C_(3~7)椎弓根通道内切圆半径在2.79~3.89 mm之间。(2)通道长度、外偏角随着边界深度的增加而增大。(3)C_(3~7)的Ac最大值出现在70%边界深度。(4)B点到正中矢状面、冠状面的距离都随着边界深度增加而增大。(5)B点、C点棘突末端的距离随着边界深度增加而增大。结论颈椎椎弓根螺钉进钉参数与棘突的三维关系,为经皮微创椎弓根螺钉固定器械设计提供依据。
[Abstract]:Objective to study the three-dimensional relationship between pedicle screw entry parameters and spinous process of cervical vertebrae. Methods the cervical CT reconstruction model of 20 healthy adults was imported into UG imageware 13.2for 70%. The 90% boundary depth was used to measure the radius of pedicle canal screw, the angle of lateral deviation, the length of channel, the angle between channel and sagittal plane and horizontal plane. The angle between the intersecting point of the screw axis and the coronal plane and the pedicle of the pedicle. Results the distance of spinous process. Results the length of the pedicle canal was 2.79 ~ 3.89 mm and 2.79 ~ 3.89 mm. The maximum value of ac of the outer deflection angle increases with the increase of boundary depth.) the maximum value of ac appears in the 70% boundary depth. 4, B point to the median sagittal plane. The distance of coronal plane increased with the increase of boundary depth. The distance between the end of spinous process at point C and point C increased with the increase of boundary depth. Conclusion the relationship between the screw entry parameters and spinous process of cervical pedicle screw is three dimensional. To provide the basis for the design of percutaneous minimally invasive pedicle screw fixation apparatus.
